We have already seen the iPhone 4 and other iOS devices running Apple’s Siri, which comes exclusively with the iPhone 4S, and yesterday we heard that Apple has no plans to bring Siri to other iOS devices.
Now it would appear that the guys over at iFixit may have discovered the reason why Siri is only available on the iPhone 4S, as it features a different proximity sensor than other iOS devices.
So we began to ponder: why is the 4S so interested in our faces’ whereabouts? Well, we believe the answer lies with our new search-servant Siri.
Siri is ready and waiting to answer her master’s beck and call at any time. And in order to be as attentive as a personal assistant ought to be, Apple had to design the proximity sensor to be as vigilant as Big Brother, but as cute as Little Sister. So whenever the screen is active, the proximity sensor is active too. Thus, whenever you raise the iPhone 4S to your face, Siri is ready to take orders.
So that could possibly explain why Apple has decided to to release Siri as a software update, and we suspect it will come along with the next generation iPod Touch and also next years iPad which will probably feature the new sensor.
Apple has now announced the iPhone 5, have a look at our article on the difference between the iPhone 4S and iPhone 5 to see all about the new iPhone 5.
